PYLARIFY TRUVU vs TECHNECOLL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PYLARIFY is a PSMA-targeted PET imaging agent composed of a urea-based PSMA ligand (piflufolastat) labeled with fluorine-18. It binds to prostate-specific membrane antigen (PSMA) on prostate cancer cells, allowing PET imaging for detection of PSMA-positive lesions.
TECHNECOLL is a collagen-based hemostatic agent that promotes platelet aggregation and activation of the coagulation cascade, leading to thrombus formation at bleeding sites.
1 mg/kg intravenously every 3 months.
Intravenous: 250-500 mg every 12 hours; maximum 1 g/day.

Terminal elimination half-life: approximately 77 hours (range 68-85 hours) in patients with prostate cancer. This supports a 2-week dosing interval for single-photon emission computed tomography (SPECT) imaging.
Terminal elimination half-life 6.2 hours; clinically, steady-state reached in 24-30 hours
Renal excretion: approximately 93% (3% unchanged, 97% as metabolites). Fecal excretion: approximately 5%. Biliary excretion is negligible.
Renal: 95% unchanged; biliary/fecal: 5%
